CLEVIS ATTACHMENT FDR PLONSQ ee s-4o.

Specification of Letters Patent.

Patented Sept. 6, 12921..

Application filed February 13, 1926. Serial No. 358,320.

To all whom it may concern:

Be it known that I, FRED W. IVoLrnR, a citizen of the United States,residing at Cuero in the county of De Witt and State of Texas, haveinvented certain new and useful Improvements in a Clovis Attachment forPlows, of which the following is a specification.

This invention relates to improvements in clevises and more particularlyto a device of this character especially designed for attachment toplows whereby to facilitate suchvariations in the line of draft as toproperly gage the depth of the plow point when working in differentkinds of ground.

A further object is the provision of an adjustable clevis attachment forplows which, due to its simplicity and comparatively small number ofparts may be readily applied to substantially any conventional type ofplow and which, when applied, is conveniently ac cessible and operableby the plow operator.

With these and other objects in view as will appear as the descriptionproceeds the invention comprises the novel features of construction,combination and arrangement of parts as will be hereinafter fullydescribed in the following specification and set forth withparticularity in the claims appended hereto.

Figure 1 represents a perspective view of the invention applied to use.

Fig. 2 represents a perspective view of the sectional and adjustablesegment supporting plate removed.

Referring to the drawing in detail, wherein similar reference numeralsdesignate corresponding parts throughout the several views, the numeral5 indicates a conventional type of plow equipped with the usual draftbeam 6 and the rearwardly diverging hanhles 7, the front terminal of thedraft beam 6 being provided, as usual, with draft plates 8 pivotallyconnected at 9 with the terminal of the beam.

In applying my invention to the plow, a pair of forwardly convergingbrace rods 10 are secured at their rear terminals to the opposed handles7 and are connected at their forward extremities with the beam 6directly above the foot thereof. A V-shaped attachin cli 11 is rigidlyfastened to the vertica ly fisposed portion of the beam 6 and supports abearing plate 12 for the upwardly extending hand lever 13.

The hand lever is provided with an approvedtype of locking device 13designed to cooperate with a rack segment 14: which is bolted orotherwise secured at one terminal to the beam 6 and is adjustablysecured at its opposite terminal by a bolt or equivalent fasteningelement 1 1 passed transversely through the registering slots 17 formedin a pair of companion supporting members 15 the terminals of which arerecessed at 16 to accommodate the opposed brace rods 10 whereby the rearterminal of the segment 14 is supported in operative position. The boltby which the terminal of the segment 14 is fastened is also utilized toclamp the companion plates 15 together to maintain relative adjustmentthereof and the terminals of the plates are preferably provided withdepending fingers which embrace the rods 10 and are apertured toaccommodate bolts whereby the plates are maintained in adjusted positionwith relation to the brace rods.

The relative adjustment of the companion plates 15 is essential owing tothe fact that the distance between the rods 10 varies according to thespace between the plow handles on various types of plows.

The upper and lower portions of the clevis plates 8 are connected withlinks 18 having connection with the upper and lower terminals ofparallel cross arms 19. A coupling plate 20 is connected with the lowerextremities of the arms 19 and is provided with a series of spacedapertures 21 adapted to selectively receive the angular front terminalof a connecting rod 22 which extends rearwardly from the plate 20beneath the plow beam 6 and is connected with the hand lever 13 at apoint intermediate the segment 14 and the supporting plate 12.

From the foregoing it is evident that I have provided a clevisattachment for plows permitting quick and convenient adjustment of theclevis plates with relation to the draft beam whereby the depth of theplow point may be varied as desired and furthermore, due to thecomparatively small number of parts and their simple construction it ispossible to conveniently apply the attachment to practically anyconventional type of low.

at I claim is:

1. A draft clevis attachment for plows comprising pivoted clevis plates,a hand lever, parallel cross arms, links connecting the cross arms withthe clevis plates, a coupling plate secured between the extremities ofthe cross arms having a series of apertures therein, means connectingthe hand lever with the coupling plate and selectively engageable in anyone of the apertures therein, and means for locking the lever inadjusted position.

2. In a clevis attachment, a pivoted hand lever, means connecting thehand lever with the clevis, means for locking the hand lever in adjustedposition, said locking means including a rack segment, brace rodsattachable to the handles and beam of a plow, and adjustable companionplates engaged with the brace rods and supporting the segment.

3. In a clevis attachment, a hand lever, means connecting the hand leverwith the clevis, brace rods attachable to the handle and beam of a plow,adjustable supporting plates detachably engage with the brace rods, andmeans to lock the lever in adjusted position, said locking meansincluding a rack segment supported at one terminal by the adjustableplates and engageable at its opposite terminal with a plow beam.

4:. In a clevis attachment, a hand lever, means connecting the handlever with the clevis, means for pivotally attaching the hand lever to aplow beam, companion brace rods attachable to the handle and beam of aplow, companion supporting plates provided with registering longitudinalslots, terminal fingers carried by the companion plates embracing thebrace rods, said plates being capable of independent adjustment tocompensate for variations in the angularity of the brace rods, a racksegment attachable at one terminal to a plow beam, means carried by thelever and coacting with the segment to maintain the lever in adjustedposition, and means carried by the rack segment coacting with theslotted portions of the companion plates to maintain the seg ment inposition and to secure the plates in adjusted position.

In testimony whereof I aiiix my signature hereto.

FRED W. WOLTER.
